以雷笋笋肉及加工后的下脚料笋壳等为原料，探讨了制取雷笋膳食纤维的最佳工艺条件。通过正交试验设计，采用绿色木霉发酵法制备雷笋膳食纤维，并对其化学成分、持水力、溶胀性、对重金属束缚能力等特性进一步研究。结果表明：最佳发酵条件为8％的接种量，于32℃，pH为7．0条件下培养48 h；产品的膳食纤维含量为85．23％，可溶性膳食纤维为30．43％，持水力和溶胀性分别达到7．82 g／g和689 mL／g，对重金属Cd2＋和Pb2＋的最大束缚量分别为38．8μmol／g和37．4μmol／g。
以雷筍筍肉及加工後的下腳料筍殼等為原料，探討瞭製取雷筍膳食纖維的最佳工藝條件。通過正交試驗設計，採用綠色木黴髮酵法製備雷筍膳食纖維，併對其化學成分、持水力、溶脹性、對重金屬束縳能力等特性進一步研究。結果錶明：最佳髮酵條件為8％的接種量，于32℃，pH為7．0條件下培養48 h；產品的膳食纖維含量為85．23％，可溶性膳食纖維為30．43％，持水力和溶脹性分彆達到7．82 g／g和689 mL／g，對重金屬Cd2＋和Pb2＋的最大束縳量分彆為38．8μmol／g和37．4μmol／g。

The dietary fiber was extracted from the shell of bamboo shoot ( Phyllostachys praecox f.preveynalis) by using the method of fermentation with Trichoderma viride, the optimal extracting technique was explored through orthogonal experiments , and the properties of the extracted dietary fiber were further studied .The results showed that the optimal fermentation conditions were in-oculum size 8%, and culture for 48 h at 32℃and pH 7.0.The obtained fermentation product contained 85.23%dietary fiber and 30.43%soluble dietary fiber.Its water-holding capacity was 7.82 g/g, and swelling capacity was 689 mL/g.The maximum con-straint quantity of the product to heavy metals Cd 2+and Pb2+was 38.8 μmol/g and 37.4 μmol/g, respectively.
